Only thing I see on this system is that the AR7000 comes in at a slightly higher weight then the AR6000. If one was looking to watch the weight on a smaller electric setup the AR6000 would be the better option.

Great effort from Spektrum, but disappointing that flight modes (1 or2) cannot be selected from software and and from other threads there seems to be a heat/power problem requiring a more efficient voltage regulator?

The lack of mode 1/mode 2 selectability may be a problem for some people but the voltage regulator is most definitely not a problem... changing it to a switching regulator is a mod undertaken by thrillseekers who don't mind voiding their warranties and feel the need to run their tx continuously for 9 hours instead of 6.

Chrome Monokote Not a Problem

I am building an electric powered 48"w/s Cessna 140. I contacted Horizon/Spectrum to ask if chrome monokote would interfere with DX-6 transmitter signals, they assured me that there would be no problems. This is a relief in that chrome Monokote scrubbed with a green Scotchbrite pad gives a scale-like alumininum look or leave it alone for a polished aluminum mirror look.

Yep we do the same but for $50 most opt for the $120 worth of digital servos to use in another project and I hate getting stuck with tons of open servos and we just don't like selling opened servos that have been taken out of boxed sets. Our customers always question this even though a lot of folks don't mind.

We have on the other hand been asking for and will continue to ask for a "Factory" packed version without the servos.

charge polarity

I wonder if the transmitter charge plug is still reversed in the DX7, compared to all the other brands of radios? I have never seen any sense in that.. But I guess if this fills my need for the rest of my life it won't matter. Brian Smith

While I appreciate the larger NiCad pack in the transmitter. I've been upgrading my transmitters (which will be for sale shortly) with 3S LiPo/Lithium ION packs. The voltage is a bit higher than a typical Nicad. I know I've voided my warantee, but do you know if this would damage the Spektrum systems? I wasn't sure if the circuits would handle the extra voltage.
